LL204
LINEAR INTEGRATED CIRCUIT
DUAL OUTPUT FLASHER
DESCRIPTION
The UTC LL204 is a dual output stages flasher designed as a
relay driver for flashing light control in automotive applications. Both
sides direction indicator input with only a small control current makes
switch contacts for small loads possible. Each side of the vehicle is
controlled separately.
DIP-14
The construction of the hazard switch could be simplified due to
hazard warning input is separate. The flasher will dramatically
increase the flash frequency by a typical ratio of 2:1 if lamp fault is
detected. The UTC LL204 can be directly connected to the battery
due to extreme low current consumption.
SOP-14
FEATURES
* Temperature and supply voltage compensated flashing frequency
* Frequency doubling indicates lamp fault.
* Two relay driver outputs with high current-carrying capacity and low
saturation voltage
* Minimum lamp load for flasher operation: ≥ 1W
* Very low sensitivity to EMI
* Extremely low current consumption<10μA ( at switches open)
* Reverse polarity protection
* Three control inputs: left, right and hazard warning
